过去5年已证明β—阻滞剂治疗变异型心绞痛不能达到典型心绞痛的类似作用,甚而可加重发作,外科疗效更差。形成这些情况的原因之一,是冠状动脉痉挛。变异型心绞痛冠状动脉痉挛发生率约20～87％,尤其采用甲基麦角新硷诱发试验后痉挛发生率更高,作者42/45例有之(发生率93.5％),因此痉挛是变异型心绞痛重要而常见现象。本文报告采用硝苯吡啶及冠状动脉旁路手术合并神经丛切除 The past five years have demonstrated that beta-blocker treatment of variant angina does not achieve the similar effects of typical angina and can exacerbate the seizures even worse. One of the causes of these conditions is coronary artery spasm. Variant angina pectoris Coronary artery spasm rate of about 20 to 87%, especially after using methyl ergometrine induced test spasm higher incidence of the authors 42/45 cases (93.5% incidence), so spasm is variant angina Important and common phenomenon. This report reports the use of nifedipine and coronary artery bypass surgery combined with nerve plexus resection
